This system can be considered as a radical expansion strategy for the Sky ecosystem, and I estimate that the overall product structure of Sky will change in the future. At present, 15 million USDC has been deployed to Spark Prime, which is the first capital of Prime and invested in M1 Capital. M1 uses this capital to run delta neutral strategy in CEX+DeFi parallel. Through Prime, Sky may gradually need to invest its money, and its core logic is to create a global Cross Marking of on chain and off chain, treating all borrower positions as a whole investment portfolio, whether your position is on Binance cex, Pendle, or Curve, it counts as a whole. For example, if you hold ETH (or LST) in DeFi and short PERP in CEX, the system will automatically recognize delta neutral hedging and only calculate margin based on net exposure, instead of fully occupying each position. This is highly efficient and helps traditional institutions to open up on chain entry points in one system. This introduces higher capital efficiency, higher returns, and also brings about system complexity. However, this expansion is likely to bring new growth and new customers, as the market and customer base it faces are completely different. But for the original Sky deposit users, they need to consider whether they can accept this risk, so another thing to pay attention to is that Sky will introduce a hierarchical mechanism in the future, similar to junior/junior tranche, which provides advanced risk deposits on top of savings, with higher returns but higher risks. This also preserves the original low-risk savings system and plays a certain degree of isolation in risk control. So Sky is no longer the original MakerDAO, it's a completely new system.
